Smoking and Tobacco
Clearing All By-Products Out of Your System..
I smoked from August 2004 to January 2006 when I finally quit as a new year’s resolution (a total of 1 year and 5 months). I still haven`t touched a cigarette since that time but have been exposed to secondhand smoke (smoked passively) from family members who smoke in my house. My question is...how long will it actually be until all the by-products accumulated in my body from smoking have totally disappeared and any damage caused in my body from smoking will be totally reversed? Can my body ever be totally smoke free and will the damage ever totally be reversed so that there won`t be a trace of smoke in my lungs?
Congratulations on quitting cigarettes and staying smokefree!
The components in cigarette smoke are many but include carbon monoxide, nicotine and its breakdown product, cotinine. The half-life of nicotine is about 2 hours and the half-life of carbon monoxide is about 4 hours. So clearly - in 17 months these have been eliminated from your system. However, the impact of smoking on blood vessels, lungs and other body parts takes more time to recover.
The 2004 Surgeon General's report details the benefits of quitting.
Some examples are listed:
Heart disease - A year after you quit, your risk of coronary heart disease will have decreased by half. After 15 years, the risk will be nearly that of a non-smoker.
Circulation - Your stroke risk is reduced to that of a nonsmoker 5 to 15 years after quitting.
Lungs - Two weeks to three months after smokers quit, lung function starts to improve. Two weeks to three months after smokers quit, coughing, sinus congestion, fatigue, shortness of breath decrease.
The risk of lung cancer decreases by as much as half ten years after quitting smoking completely. The risk of death from chronic obstructive pulmonary disease (COPD) is reduced after quitting smoking completely.
After smokers quit, they eventually return to a normal rate of decline of age-related lung function. Ten years after smokers quit, the risk of lung cancer drops to nearly one half that of a smoker. Smokers who quit lower their risk of bronchitis and pneumonia.
A poster detailing the benefits of quitting (2004) can be found on the Surgeon General Report site
